EXPEDITED PERMIT PROCESS FOR SMALL.SCALE PV SYSTEMS STANDARD STRING SYSTEM The information in rhis guideline is intended to help local jurisdictions and confractors identii/ when PV sysrem installations are simple needing only a basic review and when an installation is more comple)(. It is likely that 50 % -75% of all residenrial slstems will comply with these simple criteria. For projects that fail to meet the simple crireria. resolution sreps have been suggested to provide as a path ro perrnir approval. Requbed InJoflnation Jor Pennit: 1. Site plan showing location of major components on the property. This drawing need no( be exactly to scale, bur it should represent relative location of components at site (see supplied example site plan). PV arrays on dlvellings with a 5'perimeter space at ridge and sides may not need separate fire service review. 2. Electrical diagram showing PV array configuration, wiring system, overcurrent protection. inverrer disconnects, required signs, and ac connection ro building (see supplied standard elecrrical diagram). 5. Specifrcation sheets and installation manuals (if avallable) for all manufacrured components including, but not limited to, Pv modules, inverter(s). combiner box, disconnects, and mounting system. Step 1 : Structural Review of PV Array Mounting System Is the array to be mounted on a denned, permitt€d roof structure? E Yes E No U No d.ue to non4ompliant rooJ or a gound mount, submit completed worhsheet lor the strucntre wRS I . Roof Information: I . ls the roofing tvpe lighrweighr (Yes = composition, lighrweighr masonry, meral, erc. ..)Yes, it is composite shingle IJ No, submit completed worksheet lor rool sffucture LvfiSl (No = heavy mdsonry. slate, etc. . .) 2. Does the roof have a single roof covering? Elyes Eno If No, submit completed worksheet for roof structure wRSl. 5. Provide merhod and type of weatherproofing roof penetrations (e.g. flashing. caulk)flashing and/or caulk M ount ing Sy s t ern Inform at i on : I . Is the mounting structure an ejgineered product designed to mount PV modules with no more than an 18" gap beneath rhe module frames? lll yes LJ tlo Il No, provide deta.ils of structural attachment certiled by a design proJessional. 2.
